Legalese now - skip the following part by bearing in mind that your work should be original and preferably non-copyrighted :)
All contributions must be covered by an appropriate License agreement such as the Creative Common Attribution-ShareAlike 3.0 License. Clearly state a license and your preferred method of attribution.
Submissions must respect artwork licensing. If your submissions consist of artwork created by other people, please make sure the license of the original work you incorporate is compatible with xPUD and that you are not violating any of the provisions of its license. Just because a work is licensed with a Creative Commons license does not mean it is free to use (make sure you provide attribution to artists that license their work with a CC Attribution clause.)
Vectors will be preferred over bitmaps (i.e. svg over jpg/png etc).
p.s. if you don't want to attach your .svg use http://imgh.us , the only free svg host I know of.
can you make that in illustrator/inkscape instead? If not, I'll try to trace it for you. Provide a higher-res version too please.
